The THT-ZT transformer neutral grounding resistor cabinets are applicable to the transformer neutral points of 6~35KV AC power grids to achieve the neutral point grounding via resistor.

2, Product feature


  • Incase resistor processing adopts special high resistance alloy resistors, molding, grid structure, argon arc welding, the joint quality, surface smooth, neat; the grid structure (figure A) and Up and down modular installation, together constitute the inside and outside air from the circulating cooling system (figure B), To ensure the resistor sufficient heat dissipation.
  • Insulation parts selectehigh quality phlogopite gasket that can assure resistor with good insulation and mechanical locking strength; Traditional porcelain insulation parts is worse than mica gasket, including easy damaged in the installation, use and transportation

2)other electrical accessories in cabinet

  • Current transformer which adopts famous brand CT product is stabilizationand reliabilty
  • Neutral intelligent control system, can monitor the neutral unbalance current,the temperature change of resistor, resistance ark, and record the grounding current, grounding time, temperature change of resistor, resistance , grounding number, and provide communication port.
  • Temperature and humidity heater which control set value by adjusting the temperature and humidity controller, start-up heater heating and destruction of condensing fog cabinet, in order to prevent condensation fog inside.

3)cabinet structure

  • It adopt stationary type structure that each component combination step by step . the bottom of cabinet adopt that national standard box ironarewelded forming ,other components all adopt Sheet Metal machining technology that cause no stress accumulation between components . it ensure the integrity and fastness of cabinet
  • Speaking from the protection degree of the cabinet, the protection degree of cabinet can be made from IP00 to IP55 that suitable to site environmental as per the cabinet installation place . Adopting special built-in type structure for the door,outdoor cabinet that the top are designed with rainhat . the cabinet inside has special Letter of the ventilation and outside has Scales pore structure design,it ensure that resistor inside ark can be sufficient heat
  • The nameplate adopt theart ofstainless steelengraving whichcause the nameplate to mark clearly wearproof,easy Clean,durable in use.
